This invention relates ,to improvements in hand brakes.

One object of the invention is to provide ar simple and efficient handbrake for railway 5 cars, which is particularly adaptedfon use on flatand logging cars,andwherein.the

brake staff may be swung yfrom verticalto horizontal position attheside' ofthe car so as to clear the projecting'portions of lumber,logs, or the. like with which the carisloaded.

A more specific object of the invention is to provide a device of thecharacterindicated including a chain windingdrfum carrying a drivenmeans, anda.brakestaffy carryinga driving means adapted toengage thedriven means, `whereinthe drnm is mountedfor rotation about a fixedaXis,th e stai is` mounted for swinging movement from'a vertical to ahorizontal position, andl the driving means is adapted tooperativelyengage the driven means in eitherof said positionswithequal efliciency.

Other objects and advantages oft-he invention will more clearly appear,rorntheder scription and claimshereinafter following.

In the drawing forming `a part of this specification, Figure 1isfanfend. elevational view of a portion of a flat car, showingrmyimprovements in connection therewith., Figvy ure 2 is a vertical,sectional view corresponding .substantially tothe line=22 of Figure 1,the rotary parts. being shownL asVv moved through an arcof 90"= from,the-position shownjinFigure 1. Figure 3, is a vertical, sectionall viewcorresponding, substantially to the line 3 3 0f Figure 2. And Figure isa horizontal, sectional vview correspondingsubstantially to the line 4 4of Vliligure 3.

VIn said drawing, 10 indicates the, usual floor of the Hat car, l1 theend sill to which is attached theY brakemanls platform 12, and 131 oneof the stake receivingsockets which are ixedto the sides of the car. v

The improved brake mechanism, vas shown, comprises, broadly, a brakestaff A; a hand wheel B; a combined drvinggear andbearingY member C; abrake drum, D; afloeking collar E; a pivoted support F; and a pairoffbrackets G andH. g

The 'drum D isin the form oa two part hollow, cylindrical sleeve, the.sleeve being divided engiudinaiiy, tiresectiens 13 'ofthe sleeve `beingexact counter parts. The sleeve' D;is mounted for rotation about an,axisldilse posed in a plane parallel to the end of the.

carjandis arranged atan angle of 4:50 tothe; vertical. Thelower end ofthe drum D is re duced, as indicated at; 14, to "provide a bearingportion journaled, in thelowerl end of the bracket 15 projectingdownwardly from the bottom of the car and Xed to the end sillfll`byrivetsorany other suitable fas# tenin'g, devices. v'The bearingportion 14 gis also divided longitudinallyeach part ofthe same beingformedI integral; with fthe'. correspending section 13 of thedrum, Theupper end portion of the ,sleeveVK forming thedrum D; lsjournaled in valbearing meinber- 16 formed on the outer endof an arm IZ'lat- 1 erallyprojecting' from they brackety-f-G 'securedto lthe end sill 11 by rivetsor any other suitablev means; At, its;t 1pperend,;the drum D yisprovided witha beveledringfgear 18, .the gear, 18. being. cmnjposedyof.V two Sections each of which is` `formed integral with the corr esponding` section 13 of the drum.I The f vupper end, ofthe drum D is alsoprovided ing formed.in,eachlsection,13;I Theisocketl` 1 9 is preferablyAet vSpherical shape with the center thereofA in alillelflflellt` withthe-taxis,v of the drum.

square' portion 22 of thestaff A, to 'which it is rigidly secured `as bya" pin Qilextencling transversely through the Castille andi the of thecasting@ has a Cylindrical 'ex'terir and is jounaled 'in ahorizontallyarend icc Square Partien" 0f the Stait; Thefapperridrbracket F, which is pivot-ally mounted on the bracket Gr, the latterbeing provided with a boss 26 adapted to receive the trunnion 27extending laterally from the former and held in position by a cotter pin28. Immediately below the cylindrical portion of the casting Vwardly.The conical portion of the casting C is formed with'a series ofperipheral teeth 31 thereby presenting a bevel gear adapted to Vcoactwith the teeth ot thebeveled ring gear 18.

The stai A is also provided with a-ratchet wheel 32 of well-knownconstruction mountedfon the square portion of the former for rotationVtherewithv and is adapted to bear on the upper surface of the plate 25.Av

' lockingfdog 33, adapted to coact with the ratchet wheel 32, ispivotally mounted on the plate by the bolt 34.

ToV hold the stan? in vertical position the` following means isprovided. Y The bracket Y G is formed with an upper, laterally eXtendfing, arm 35 terminating in a hook shaped portion 36 providing a sockethaving an upstanding curvedflange 37 adapted to engage within an annularflange 38 downwardlyeX- tending from the collar E slidably mounted forvertical movementon the staff A. It will be evident that when the flangeof the collar Y is engaged over the flange 37 of the arm 35, the stallwill be positively held in its vertical position. To Vdisengage thestaff from the socket of the bracketv 35, the, collar E is movedupwardly on the staff Athereby disf engaging the same from theflange 37whereupon the staff may be swung downwardly to the horizontal positionshown in dotted lines `in Figures 1 and 3.

lTo retain thestai 'A in the horizontal poel s ition, the bracket H isprovided, the same being `in the form of a U-shaped hook memberrigidlysecured to the end sill'11` by rivets. The short arm oi" the Uportion ofthe bracket H is provided with a spring clip L10 adaptedV to work in aslot in the arm ofv the brackety and spring into position over the stallwhen the same rests within the hook Yso portion of the bracket. Topermit the brake staff A to be swung into position, the brakemansplatform 12 is pivotally mounted so as to swing upwardly, thezsame beingsupported bya pair of brackets 41 iiXed to the end sill 11 by rivets andstraps 42 secured to the lower side of the platform and pivotallyconnected with the brackets 41.

In assembling the device, the spherical end n 19 ofthe. combined bearingand gear C is first engaged within the socket portion of one of thesections 13 of the brake 'drum D. The opposite section 13 is thensecured in-position by the rivets 120 and the eye-bolt 21 therebyretaining the spherical end permanently wit-hin the socket. The pivotedbracket F is next assembled with the combined gear and bearing member Cby inserting the cylindricalbearing portion of the latter within Vtheopening providedin the plate. The stan;1 A, after having the ratchet andcollar E yplaced thereon, is then assembled with the member C. i Y y'The operation ofthe device is as follows. Vhen the brake staii is in thefull line position shown in the drawing, that is, when the same isdisposed in'vertical position, rotation of the hand wheelwill efliectrotation of theY chain winding drum in either direction through theinter-engaging gears C and 187 in a wellknown manner. WV hen itisdesired to operate the brakes from the side of lthe car, the iange ofthe collarE is disengaged f from the flange 37 of the bracket 35 andVthe statt A swung to the .position shown in dot-ted lines in Figures 1and3, thebrake'- mans platform 12 being first swung upwardly out oflthel way. vlt willpbe evident d that in swinging the stati' A from thevertical tothe horizontal position, the gear teeth. 31Y will first bedisengaged tromthe upper side of the ring gear 18 and reengaged atthelower side thereof when the stafi'reac-hes the horizontal position.'y Inthe swinging movement ot the stati, the pivoted bracket F together withthe locking dog and ratchetwheel will be Acarried therewith, as clearlyshown in Figure 1. It will be evident that rotation of the locking dogaround the axis'of the stafi' is efiectively prevented by n jects abovethe level of the floor so all posi sibility of interference withprojecting material is absolutely eliminated. Furthermore, the handwheel in fthe Vlowered position of the staff is ata convenient andaccessible vpoint forthe brakeman, whether he be `running along theground or on the usual step. I have herein shown and described .what
